HOW IT WORKS

Each round will have 3 questions. The topics for the three questions will be listed at the beginning. You will be able to wager 1, 2, and 3 points once each per round. For instance, if you bet 3 points on the first question, you cannot use it again that round. In the 2nd round, points are doubled. In the 3rd round, points are tripled. At the end of three rounds, the team can pick how much to wager for the final question. Winner is whoever ends up with the most points.
